Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, specifically to a waterproof encapsulation structure for light strips. Background Technology

[0002] LED light strips are products in which LED light-emitting diodes are mounted on a strip of flexible printed circuit board (FPC) or rigid PCB. They are strip-shaped, have a long lifespan, are energy-saving and environmentally friendly, and have been widely used in various decorative industries. The advantage of LED light strips is that they can be cut to size according to needs, making installation and application more flexible.

[0003] LED light strips mainly consist of a circuit board and LED light-emitting elements. The circuit board has printed circuitry, and depending on the manufacturing process, the LED light-emitting elements are packaged or soldered onto the circuit board and electrically connected to the printed circuitry. Leads are soldered to the circuit board's terminals to connect to the power adapter. Current LED light strips are mass-produced using automated soldering, and the solder joints lack waterproofing measures. This leads to short circuits caused by rainwater at the solder joints between the light strip and the adapter, resulting in low waterproofing ratings. Furthermore, the tensile strength of the solder joints and leads is low, leading to product stability issues. Therefore, the existing technology requires improvement and development.

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, the waterproof packaging structure for a light strip according to this utility model includes a base strip 1 and a housing 2. The base strip 1 is provided with an LED light-emitting element, and one end of the base strip 1 is a terminal 11 with a lead wire soldered on it. The housing 2 is provided with two partition beams 21. One partition beam 21 forms a first area 211 with the first end of the housing 2, and the other partition beam 21 forms a second area 212 with the second end of the housing 2. The two partition beams 21 are spaced apart to form a sealing area 213 between them. The base strip 1 passes through the first area 211 or the second area 212, and the base strip 1 is connected to the corresponding partition beam 21, so that the terminal 11 of the base strip 1 is inserted into the sealing area 213, and the sealing area 213 is filled with insulating sealant.

[0021] It is understood that the baseband 1 described in this utility model includes an FPC and a PCB circuit board. The baseband 1 is equipped with LED light-emitting elements (not shown in the drawings), and the terminal 11 on the baseband 1 is equipped with leads (not shown in the drawings). Two basebands 1 can be respectively installed at both ends of the housing 2, and the two basebands 1 are connected by leads. Alternatively, a baseband 1 and a power adapter can be respectively installed at both ends of the housing 2, and the baseband 1 and the power adapter are connected by leads.

[0022] Specifically, the housing 2 is typically a cuboid structure with two spaced-apart partition beams 21 inside. These beams divide the interior of the housing 2 into a first zone 211, a second zone 212, and a sealing zone 213. Both the first zone 211 and the second zone 212 have insertion ports, allowing the baseband 1 to pass through either zone. This allows the terminal 11 to cross the partition beams 21 and be positioned within the sealing zone 213. The sealing zone 213 is filled with insulating sealant, sealing the solder joints on the terminal 11 and simultaneously increasing the connection strength between the baseband 1 and the housing 2. Preferably, the solder joints on the terminal 11 face downwards.

[0023] The partition beam 21 is fixedly mounted on the bottom plate of the box body 2. Both ends of the partition beam 21 extend to the inner walls of both sides of the box body 2. An adhesive strip 22 is positioned above the partition beam 21. The adhesive strip 22 is parallel to and spaced apart from the partition beam 21, with both ends connected to the inner walls of both sides of the box body 2. The baseband 1 passes between the partition beam 21 and the adhesive strip 22, allowing its terminal 11 to be inserted into the sealing area 213. It is understood that the baseband 1 includes both an FPC and a PCB circuit board, thus having a certain thickness. After the baseband 1 passes through the partition beam 21, an adhesive strip 22 is placed above it to increase the depth of the sealing area 213. The solder joints on the terminal 11 face downwards, ensuring that the insulating sealant in the sealing area 213 completely covers the baseband 1 to guarantee sealing reliability.

[0024] Furthermore, the box body 2 is provided with a cover plate 23, which is attached to two adhesive strips 22. The two ends of the cover plate 23 are respectively connected to the inner walls of both sides of the box body 2, thus allowing the sealing area 213 to be independently set. The adhesive strips 22 can be made of rigid insulating bakelite or elastic composite materials, such as plastic, rubber, and other insulating materials. The box body 2 is provided with two partition beams 21 and two adhesive strips 22. The base band 1 passes through the gap between the partition beams 21 and the adhesive strips 22, thus forming... Figure 2 The sealing area 213 shown is covered by a cover plate 23 on the two adhesive strips 2, so that the sealing area 213 is closed.

[0025] The purpose of the above specific arrangement is that, during assembly, the baseband 1 is inserted through the opening above the box 2 and placed on the partition beam 21. Then, the adhesive strips 22 are paired and placed on the baseband 1. Next, insulating sealant is injected into the sealing area 213, and finally, the cover plate 23 is placed over the sealing area 213 to seal it. It is understood that the amount of insulating sealant injected into the sealing area 213 is usually greater than its volume. Therefore, after sealing the cover plate 23, there will be some overflow of insulating sealant. Since the two sides of the sealing area 213 are the first area 211 and the second area 212, the overflow of sealant will not affect the product performance.

[0026] Furthermore, when the cover plate 23 fails to fit tightly against the rubber strip 22, the insulating sealant overflows from the gap between the rubber strip 22 and the cover plate 23, resulting in a certain amount of insulating sealant between the cover plate 23 and the rubber strip 22, and between the rubber sleeve 22 and the base strip 1, making the sealing performance in the sealing area 213 more reliable.

[0027] Preferably, guide blocks 24 are provided at both ends of the partition beam 21. The guide blocks 24 are vertically arranged on the inner sidewall of the box body 2, and the guide blocks 24 are provided with toothed grooves 240. The base strip 1, the adhesive strip 22, and the cover plate 23 are all provided with toothed grooves 240. The cover plate 23, the adhesive strip 22, and the base strip 1 are stacked sequentially from top to bottom, and the cover plate 23, the adhesive strip 22, and the base strip 1 are respectively engaged with the guide blocks 24 through the toothed grooves 240. Specifically, the toothed grooves 240 are composed of continuous grooves and protrusions. The guide blocks 24, the base strip 1, the adhesive strip 22, and the cover plate 23 are all provided with toothed grooves 240, so that the base strip 1, the adhesive strip 22, and the cover plate 23 can all be adapted to the guide blocks 24 to achieve a snap-fit ​​connection, which facilitates the assembly and positioning of the above components. In particular, the guide block 24 and its toothed groove 240 are vertically arranged, so that the base belt 1, rubber strip 22 and cover plate 23 can be installed into the box body 2 from top to bottom in sequence.

[0028] This utility model also includes an upper cover 25, which is provided on the cover plate 23. The top surface of the box body 2 is open, and the upper cover 25 is set on the opening of the box body 2. The upper cover 25 and the cover plate 23 are provided with positioning holes 250. A central post 26 is provided in the sealing area 213. The lower end of the central post 26 is fixedly connected to the bottom plate of the box body 2, and the upper end of the central post 26 passes through the positioning hole 250. The upper end of the central post 26 is provided with a fixing screw 27, which fixes the upper cover 25 and the cover plate 23 to the central post 26. The upper cover 25 and the cover plate 23 can be an integral structure, that is, the cover plate 23 can protrude from the bottom surface of the upper cover 25. After the upper cover 25 is paired with the central post 26 through the positioning hole 250, the fixing screw 27 fixes the upper cover 25 and the cover plate 23 on the opening of the box body 2. It is understandable that the top cover 25 and the cover plate 23 are described separately here, mainly for the purpose of differentiation. The cover plate 23 is used to seal the mating adhesive area 213, while the top cover 25 is used to seal the first area 211 and the second area 212.

[0029] Preferably, a sealing ring 28 is fitted onto the central post 26, and the sealing ring 28 is paired with the positioning hole 250. Since the diameter of the positioning hole 250 needs to be larger than that of the positioning post 26, a sealing ring 28 is first installed on the central post 26 so that during the assembly of the cover plate 23, the sealing ring 28 seals the gap between the central post 26 and the positioning hole 250, preventing the insulating sealant from overflowing from the positioning hole 250.

[0030] The first end of the box body 2 is provided with a first crossbeam 201, the two ends of the first crossbeam 201 extending to the inner walls of both sides of the box body 2. The first end of the top cover 25 is provided with a first hinge 251, the first hinge 251 and the first crossbeam 201 are spaced apart to form an insertion port connecting the first area 211. The second end of the box body 2 is provided with a second crossbeam 202, the two ends of the second crossbeam 202 extending to the inner walls of both sides of the box body 2. The second end of the top cover 25 is provided with a second hinge 252, the second hinge 252 and the second crossbeam 202 are spaced apart to form an insertion port connecting the second area 212. The first crossbeam 201, the second crossbeam 202 and the partition beam 21 are set at the same height and flush with the bottom plate of the box body 2. The first crossbeam 201 is paired with the first hinge 251 to form a socket, and cooperates with the corresponding partition beam 21 to form a first area 211; the second crossbeam 202 is paired with the second hinge 252 to form a socket, and cooperates with the corresponding partition beam 21 to form a second area 211, so that the baseband 1 passes through the first area 211 or the second area 212 and is led out through the socket.

[0031] The second zone 212 is provided with an adapter mounting slot 214. It is understood that the first zone 211 and the second zone 212 are interchangeable to achieve connection between basebands 1 and between basebands 1 and the adapter. Furthermore, the mounting slot 214 is used to install the adapter, and the adapter's interface can extend outwards from the housing 2 through the aforementioned socket. Of course, when installing the adapter, the gap between the second crossbeam 202 and the second hinge 252 can be increased to facilitate the installation of the adapter interface.

[0032] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
